WATER, CIRCULATOR FOR WATEB-COOLED ENGINES.

Application filed January 17, 1918, Serial No. 212,200. Renewed November28, 1921.

To all 'whom t may concern.'

Be it known that we, F RANK B. UrroN, a citizen of the United States,and a resident of the city of Chattanooga, in the county of Hamilton andState of Tennessee and WILLIAM C. KIRK, a citizen of the nited States,and a resident of the city of Chattanooga, in the county of Hamilton andState of Tennessee, have invented a new and useful Improvement in WaterCirculators for Water-Cooled Engines, offwhich the following is aspecification.

Cur invention relates to water cooling systems for internal combustionengines and has for its principal object to. provide a device which willeffect positive circulation of the water through the water jackets ofthe engine and the radiator. Another object of the invention is toprovide a circulator, which can be secured in place by unskilled personswithout difficulty. A. further object is to overcome the disadvantagesof the thermosyphon system by providing a device which can be includedin the ordinary thermosyphon cooling system without greatly changing itsconstruction, thus producing a positive circulation of the water. Afurther object is to provide a circulator which will be simple inconstruction and can be cheaply manufactured. v

The invention consists in a circulator for a water cooled system adaptedto be se-4 cured to the outlet of the engine. The invention alsoconsists in a device for a water cooled engine operatively connectedthereto and adapted to be secured to the water outlet of the engine forpromoting the positive circulation of the water between the engine andthe radiator. The invention also consists in the combination andarrangements of parts hereinafter described and claimed.

n theaccompanying drawings, wherein like reference numerals refer tolike parts wherever they occur,

1 is a side elevation of an internal combustion engine with a watercooling system showing a water circulator embodyi'ng our invention;

Fig. 2 is a side View of the water circulator detached;

Fig. 3 is a view of the circulator looking at the end, whichcommunicates with the water outlet of the cylinder head;

Fig. 4 is a vertical longitudinal section on 55 the line 4 4 in Fig. 3;and

Fig. 5 is an end view of the circulator with the pulley removed, partsbeing broken away to disclose the method of oiling.

Figure 6 is a horizontal sectional view 60 passing through the axis ofthe shaft 16 in -Fi ure 3.

eferring to Fig. 1 of the drawings, the gasoline engine 6 is shown inconnection with the ordinary type of thermo-syphon 65 cooling system.This system comprises a radiator 7 located in front of the engine andconnected to the water jackets of the engine by a radiator inlet pipe 8leading from the outlet end of the water jackets of the engine 6 to theupper portion of the radiator 7 and also connected to said jackets by aradiator outlet pipe 9 leadin from the bottom of the radiator to the iet side of the water jackets of the engine. The water in the radiator 7is cooled by the usual rotary fan 10 which is driven from the crankshaft by a belt 11. The positive circulation of the water between theradiator Aand the water jackets of the engine is effected by lneans of acirculator or pump. The circulator consists in a hollow body portion 12bolted or otherwise secured to the engine which is provided with acylindrical chamber 14 communicating with the water outlet 85 openinginthe cylinder head of theengine.

An inclined branch pipe 13 leading from the chamber 14 is connected tothe radiator inlet pipe 8 which leads to the top portion of the'radiator 7. Rotatably mounted in 9o propeller is arranged adjacent theopen end e5 of the chamber 14 of the circulator and when rotated forcesthe water to circulate freely between the radiator and the water jacketsof the engine. The propeller 17 is rotated from the crank shaft of theengine by means of the fan belt 11, which is lengthened out so as tooperate a pulley 18 mounted on the end of this shaft 16. The pulley 18is removably secured to the shaft 16 by means of a set-screw 19 and isdriven 105 from the fan belt 11, which is lengthened out to pass overthe pulley 18 for operatingthe same.

The bearing 15 for the shaft 16 is provided with a packing gland 20,which projects in a stufling box formed in the inwardly projectingportion 2l for holdingI the packing 22 located therein in position. Anoil cup 23 is threaded into an oil hole 24 bored in the side of thecirculator at its end and registers With a hole 25 in the packing gland20 of the bearing 15 for oiling the shaft 16. The positioning of thepacking 22 between the bearino' for the propeller shaft and the water cAamber of the circulator prevents the water from coming in contact withthe bearin thus resulting in a smooth running-water tight bearing thatpermits oillng.

One of the advantages of locating the circulator at the outlet end ofthe water jackets is that it permits the radiator fan belt to be usedfor operating the circulator pulley without disturbing the fan, radiatoror any of its connections. vThis arrangement also permits the fan pulleyto be used as a belt ti0h t(' ,"n'ei.A

:The cooling 'arrangement described in the foregoing specification isconsidered only as an "xam'ple and as being the one most general y used,but the invention is not restrict'ed thereto, the circulator beingequally aswell applicable to 'various types of water cooling' systemsfor internal combustion eng1n`es. l

Wb claii'n'th'e following as our invention.

In cinbination with the water cooling system of an internal combustionengine, a circulating unit` detachably secured to the water oi'ltl'et ofsaid engine, said unitl comprisi'ngv a hollow elbow-shaped shell havinga water chamber therein and inist and outlet openings for said. chamber,a bearing member secured to said shell, a shaft carried by said bearingmember and extending into the wall of said chai'nbe'r, a'scre'wpropeller secnred to the end of the shaft within the chamber, a drivingpulley secured to the othere'nd of said shaft, means tor lubricating theshaft bearing, a stuffing box formed by said bearing member and theshell, packing within said box, said stuft-ing box being adjacent tosaid water chamber whereby wa'ter is prevented from entering saidbearing and washing 'away the oil therefrom.

2. In combination with the water cooling system of an internalcombustion engine, a circulating unit detachably 'secured to the wateroutlet of the engine, said unit comprising a hollow elbow-shaped shellhaving a water chamber therein and inlet and out let openings for saidchamber, a bearing member' secured to said shell, a shaft carried bysaidbearing member, and extending into the wall of said chamber, theaxis of said shaft being substantially an extension of the axis of saidinlet opening, a screw propeller secured to the end of the shaft nearestsaid opening, a driving pulley secured to the other end of said shaft,an oil cup mounted on the shell and having an opening through said shellto said shaft bearing, a stuiiing box lformed by said bearing member andthe shell and adjacent the water chamber on one side and the oilconnectionv on the other, whereby water from the chamber is preventedfrom contacting with said bearing and washing away the oil therefrom.

3. In combination with the water cooling system of an internalcombustion engine, a circulating unit., detachabl'y secured to the wateroutlet of said engine, said unit comprising a hollow elbow-shaped shellhaving a water chamber therein and inlet and outlet openings for saidchamber, a substantially cylindrical member forming anv in-V tegral partof said shell and extending into the water chamber to a point adjacentan opening of said chamber, a bearing member secured to said shell, andextendingr into the cylindrical member, a shaft carried by the bearingof said bearing member, a screw propeller secured to the end of theshaft nearest said opening, a driving pulley secured to the other en'dof said shaft, means for lubricating said shaft bearing', a studing boxformed by said bearing member and the cylindrical portion of said shellpacking within said stuiiing box, said stuifing box being adjacent tosaid water `charnber whereby water is prevented from corning in contactwith said bearing and wa'shing away the oil therefrom.
